viscosity. n, pl-ties. 1. the state or property of being viscous. 2. (General Physics) physics. a. the extent to which a fluid resists a tendency to flow. b. Also called: absolute viscosity a measure of this resistance, equal to the tangential stress on a liquid undergoing streamline flow divided by its velocity gradient. It is measured in newton seconds per metre squared.
Top 10 unbelievable historical concurrencies. Viscosity is a scientific term that describes the resistance to flow of a fluid. The fluid can be a liquid or a gas, but the term is more commonly associated with liquids. As a simple example, syrup has a much higher viscosity than water: more force is required to move a spoon through a jar of syrup than in a jar of water because the syrup is more resistant to flowing around the spoon.
